摘　　要：长棘海星的暴发对我国乃至印度−太平洋海域的珊瑚礁造成了严重的破坏。鱼类捕食者被认为是控制长棘海星种群暴发的重要因素,但我国对于可捕食长棘海星的鱼类的研究尚属空白。通过采集西沙5个长棘海星暴发礁区的珊瑚礁鱼类,利用PCR技术检测了鱼肠道内容物中的长棘海星DNA,并与已报道的长棘海星鱼类捕食者进行了比较分析。结果显示,本次调查共捕获了62尾鱼,共23科36属50种。在4种鱼的肠道内容物中检测到长棘海星DNA,分别是颊吻鼻鱼(Naso lituratus)、网纹宅泥鱼(Dascyllus reticulatus)、三叶唇鱼(Cheilinus trilobatus)和赤鳍裸颊鲷(Lethrinus erythropterus)。其中颊吻鼻鱼、三叶唇鱼和赤鳍裸颊鲷为首次报道的长棘海星潜在捕食者。本研究首次鉴定了我国长棘海星潜在鱼类捕食者种类,为开发长棘海星早期防控技术提供了重要参考。The crown-of-thorns starfish(CoTS)outbreak has caused severe damage to coral reefs in China and the Indo-Pacific region.Fish predators have been considered as an important factor in controlling the population outbreak,but there is a lack of research on the fish that can prey on crown-of-thorns starfish in China.By collecting coral reef fish from five outbreak areas of crown-of-thorns starfish in the Xisha Islands,CoTS DNA was detectedin the intestinal contents of the reef fish using PCR technology,and which compared with reported CoTS larval predators.The results showed that a total of 62 fish belonging to 23 families,36 genera and 50 species were captured in this survey.CoTS DNA was detected in the gut contents of four fish species,namely Naso lituratus,Dascyllus reticulatus,Chelilinus trilobatus and Lethrinus erythropterus.Among them,N.lituratus,C.trilobatus and L.erythropterusare reported for the first time as potential predators of CoTS.This study has identified the potential predators of CoTS for the first time in China,providing important references for the development of early prevention and control techniques for crown-of-thorns starfish.
